Endstop and docking means for thermoplastic bags

摘要

In a thermoplastic bag having a reclosable fastener extending along the mouth of the bag and a slider straddling the fastener for opening and closing the fastener, the fastener including two opposing interlocking profiles along the side walls of the bag, the slider adapted to maintain straddling relation with the fastener, an improved endstop means proximate to at least one end of the reclosable fastener, the endstop means being formed from the material of the profiles and rising vertically from the fastener to a height adequate to engage the slider and prevent movement of the slider past the end of the bag. A rail extends along the length of at least one of the profiles on the outside thereof, the rail extending to a point sufficient to permit the slider to cooperate with the rail to maintain straddling relation with the fastener when the slider reaches the endstop. Docking means and methods of making endstop means and docking means are also disclosed.
